ELEVATED CARRIER.

Specification of Letters Patent.

Patented Oct. 6, 1908.

Original application filed September 3, 1907, Serial No. 390,998. Divided and this application filed January 24,1908.

' Serial No. 412,400.

To all whom it may concern:

Be it known that we, ALBERT H. NELLER and WILLIAM LoUDEN, citizens of the United States, residing at Fairfield, in the county of Jefferson and State of Iowa, have invented a new and useful Improvement in Elevated Carriers, of which the following is a specification, this ap lication being a division of i application Serial No. 890,998, filed September 3, 1907.

Our invention relates to tracks for overhead carriers and it consists of an improvement whereby cross tracks may be readily joined together or separated apart, so that a carrier may run from one track to the other or upon either track as may be desired. Also,

in other features set forth in this specification and more specifically pointed out in the claims. T

In the accompanying drawings forming a part of this specification, Figure 1 is a perspective of a track mounted in position to support a carrier, a portion of the drawing being broken away to show the anchoring device. Fig. 2 is a perspective showing cross tracks joined together so that a carrier may run from one track to the other. Fig. 3 is a transverse section on line 33 of Fig. 2. Fig. 4. is an enlarged perspective of one of the details.

Referring to the drawings, A represents a' main track which is preferably a wire stretched between two points, one generally being the building in whichthe carrier is used (not shown in drawing), and the other a post P set out in the yard. The end of the track wire is fitted with a loop and a tension bolt B, having a thread and nut on one end and a hook on the other to catch in the loop, is passed through the top of'the post. The thread on the bolt is made long so it can be adjusted to secure the required tension of the track wire. D represents an additional track wire similarly supported and arranged they are driven back and to form secure fas- V tenings for the switches.

When two switches are used at the same crossing, so as to connect the main track with both ends of the cross track, a support such as a hook H, is necessary to hold the end of one of the switches up from the main track so the carrier may run on the other switch and on .to the end of the cross track with which it is connected. The hook H may be used to hold up the end of the switch S while the switch S is connected to the track A and in this way the carrier may be run on to the opposite end of the track D. Any desired kind of a carrier O having wheels W to run on the track may be used, but it is preferable that the wheels should be mounted in yokes Y which are open on one side and that they be arranged to swivel in the frame of the carrier so they can be changed to run on either side of the track wire;

To make the change so the carrier will run on to either end of the cross track D, all that is necessary is to change the switches, as already noted, and to lift the carrier wheels W off the track (one at a time), swivel them around and place them on the track again with the yoke Y on the other side of the track. The changing of the yokes to the other side of the track wire is preferabl done while the receptacle is empty, in whic case the change is easily and quickly made. Any desired kind of key may be used to wedge the switch on to the track wire, but the form shown in Fig. 4 is preferable. Its upper side is grooved to fit the track wire, whlle its lower side is rounded to fit the inside of the switch pipe and it is rovided with 2. lug 7c which projects down t rough the slot in the pipe by means of which it may be easily driven in or out.

While the switches are being used to transfer the carrier from the track A to either end of the track D it is desirable that the track wires be held securely together. 'To effect should be cut a sufiicient length to give the this result we have provided a coupler E having on one end an open coil terminating in a projecting point i and on the other end a laterally extending hook G as shown in Fig. 2. To disconnect the wires from this position, the hooked end of the coupler is pushed back from the wire A until its body will pass down behind it. Pushing the hooked end under the wire D and up on the opposite side, the coiled end will become disengaged from the wires and they will be free to separate. When thus free to separate the main Wire A will sag so the carrier may be run on it below the cross wire D. To connect the wires together again the body of the coupler is held substantially parallel with and behind the main wire A, and immediately back of the cross wire D; or the hooked endG may be raised above the wire A, so that the point F can be passed under the wire D, on the near side of the wire A. By turning the hooked end down and under the cross wire D, and bringing it up so it will hook on the main wire, as shown in Fig. 2, the coiled end will be passed around and will hold both of the wires securely together.

1 represents a trip stop and J an end stop which are used in connection with the carrier C, and which are duly described in the application from which this was divided.

L is a log or timber which is generally planted in the ground, as shown, and M is a bolt which is passed up through the log. It has a nut and a long thread on its up or end, which end is passed up through a 110i; in the central part of a yoke N. A loop 0 is passed around the upper end of the post P so as to be above the tension bolt B on the inner side of the ost and below it on the outer side. A pin is passed crosswise through the to of the post close to the tension bolt and pre 1 erably above it, so that the loop 0 will rest upon it and be prevented from slipping down on the post. If desired, a small notch or crease may be cut on the inner side of the post so that the upper portion of the loop will catch in it.

B is an anchor wire having a loop on its upper end into which the wire constituting the loop 0 is connected. The loop 0 is preferably made with a small loop on each end of the wire composing it, and these small loops are linked into the loop on the end of the wire R. An inverted V shaped wire V, having a loop on each of its lower ends which are connected to hooks on the ends of the yoke N, is also connected in its central or V shaped portion to a 100 in the lower end of the anchor wire R. n this way the upper end of the post carrying the tension bolt B is connected to the log L, and by means of the threads and nuts on the tension bolt and on the anchor bolt M, the set of the post may be varied and the tension of the track wire A regulated to suit requirements. The threaded end of the bolt M being passed through the center of the yoke N, at a distance l'rom the loops of the wire Y, and being above the ground, the nut is easily adjusted thereon to regulate the distance from the loop O to the log L. The loops on the ends ol" the wire ll. may be made in any desired way but it is preferable to ilOll'll hooks on the ends of the. wire bent parallel to the body of the wire and then use clamps T to hold, them in position and. to prevent the connections l'rom hecoming diseng. ged. in this way the connections can be more readily made or disengaged from one another and will be securely held together.

The entire apparatus forms an extremely simple, cheap, easily arranged and ell'eclive device, and one which may be readily adapted to almost any situation. instead ot using the log L or planting it in the ground, the bolt M may be connected to any suil able holding means such as tree, a sill ol' a building or other means, such as will readily occur to those skilled in the art.

In elevated carriers, two overhead track wires crossing each other, a carriage to run on said wires, tubular switch-piece curved so the ends will co-incide with the wires, a slot out in the lower side of each end of the piece so as to lit down over the wires and means to key the piece thereon.
